Mingella Winkybunion is the sister of Gruntilda, Brentilda and Blobbelda. She took part in freeing Grunty from a prison beneath a giant Bolder. Tragically, Mingella spotted Mumbo Jumbo, who overheard the witch's plot, which caused Bottles's temporary death. Her, along with Blobbelda, assist Klungo on freeing Grunty from the boulder.

Mingella apparently died, along with Blobbelda, when a one ton weight crushed her for losing a round in Grunty's Tower of Tragedy Quiz.

Mingella and Blobbelda are mentioned in Banjo-Kazooie: Grunty's Revenge at the end of the game by Gruntilda when she tells Klungo to fetch her sisters, being Mingella and Blobbelda and starts the events of Banjo-Tooie.
